8 Claims. (Cl. 206-56) The present invention relates to a cosmeticapplicative holder particularly of the type designed to contain, projectand retract a dispensable cosmetic in cake form to be applied by rubbingthe cake against the face.

As distinguished from the lipstick type of cosmetic, which commonly isof relatively slim pencil-like shape, cosmetic cakes for application tothe face require a greater area of rubbing surface for contact with theskin, and they are more convenient to use when their face markingsurface area is of relatively long and narrow proportions because suchshape offers a choice of breadth in the marking stroke. The problem ofprojecting and retracting a cake of cosmetic whose cross-sectionalprofile is of such size and proportions, as distinguished from theusually slender, cylindrical and crayon-like lipstick, calls for a newand different kind of operating mechanism for moving the cake carriersuccessfully between projected and retracted positions.

It is an object of the present improvements to provide an applicativeholder for a cosmetic cake of relatively long and relatively narrowcross-sectional shape which shall insure a smooth action of the cakecarrier in its sliding movement even when resisted by daubings of thecosmetic that may become lodged between the relatively movable parts ofthe holder mechanism.

Another object is to decentralize the cake carrier motivating mechanismin order to take advantage of the noncircular and unequalcross-sectional proportions of the carrier for housing in rather widelyseparated relation plural motivating screws which then may actsimultaneously on the cake carrier at points well separated laterally toimpel it forcefully in sliding direction while serving also to constrainit against disalignment with its direction of sliding movement thatmight cause it to cock or jam in the guide well of its casing.

Another object is to enable the shape of the outer casing to followclosely the shape of the cosmetic cake so that the bulk and over alldimensions of the entire holder may be kept to a minimum in comparisonwith the size of the cosmetic cake held and dispensed thereby.

A further object is to afford combined functions for the roughenedsurface of a wheel handle so that it may serve both as a motiontransmitting gear and as a rotary actuator to be grasped and turned bythe fingers of the users hand.

A further object is to arrange such wheel handle coaxially with the lineof reciprocative movement of the carrier of the applicative cosmeticcake.

A further object is to provide an assembly comprising plural impellingscrews and a train of gears operatively interconnecting them so that allthese working parts may be removed from the casing by merely displacinga common thrust affording element that retains them against axialmovement when in place.

These and related objects of the improvements will ap pear in greaterparticular from the following description of a, successful embodiment ofthe invention having ref-.v erence to the appended sheet of drawingswherein:

The casing body 12 of my improved applicative holder has a hollow fullyencompassed by said body which provides a guide well 13 extending in anaxial direction and open at one axial end to permit. the projection andretraction therethrough of a cake of cosmetic marking substance 14. Thiscosmetic cake is lodged in a slidable carrier cup 15 which is preferablyovate or of elongate shape along a major axis in transverse profile, asis the cosmetic cake. Thus the top or applicative surface of the cake isof relatively large area and presents a shape which gives a choice ofwidth of marking stroke depending upon the direction and angle at whichthe cake is applied and wiped against the users face.

Carrier cup 15 is equipped with two follower lugs 16 which projectlaterally therefrom. Each of these lugs tracks axially in impellableengagement with only the nearest sides of equally pitched helicallywinding threads of impelling screws 17 when the latter turn in unison.Each of these screws is in outboard relation to and substantiallyisolated from the guide well 13. The threads of screws 17 comprisehelical tracks so engaged by follower lugs 16, respectively, that thelugs are kept on a common level to prevent cocking or jamming of cup 15in well 13. To help insure this the impelling screws are spacedlaterally apart as far as is permitted by the transverse dimensions ofthe casing.

Each impelling screw 17 substantially fills the girth of or rotatablyfits, and is axially retained within, a full length bearing hole ortransmission chamber 18 in casing body 12. Each of these bearing holescommunicates laterally withguide well 13 through narrow vertical slots19 in a partition intervening between the guide well and each of screws17. The partitions comprise walls spanning and dividing the hollow ofthe casing body into the guide well 13 and the transmission chambers 18.Follower lugs 16 are free to slide up and down in slot 19 but arerestrained thereby against turning movement about the central axis ofthe casing. Thus the carrier cup 15 is kept from turning about itsvertical axis and does not depend for this constraint upon its ovateprofile nor the fit thereof within the guide well 13, wherefore thecarrier and well might, if preferred, be round instead of ovate.

On the bottom end of each impelling screw 17 there are fixed pinionteeth 22 which are located rotatably in mesh with corresponding gearteeth 23 on the periphery of a rotary actuator'which as here shown is inthe nature of a wheel handle 24 having a multiple ridged peripheryafiording gear teeth 23. The small pitch of gear teeth 23 and theabsence of .sharp edges thereon adapt the square? threads or helically;winding finsz V lieved' unnecessary to mention or illustrate- -the= many'other'lvarieties oflconstruction by which a worn'i' like turned by thefingers of a users hand applied to di-' ametrically opposite segmentalportions of the handle which are exposed for manipulationoutside theconfines of the base1portion of casing'body 12asi'showrr in Figs. 1; 2;4; 5 and 6; Other portions' ofithe wheel-handle are concealed Within theconfines of easing body 12; the latter being circularlyirecessed at 25.to accommodate the central concealed portions ofthe wheel handler,
